C1-S1 – Capability to Service Mapping

The C1-S1 Capability to Service Mapping View depicts the underlying capabilities of a given set of Service Specifications.

Concerns Addressed

• Wrapping capabilities as Service Specifications.
• Defining the capability required from a given Service Specification.

Background

If network enabled capability is to be delivered by the orchestration of loosely couple services (i.e. a service-oriented architecture), it is important to know which services have the potential to support particular capabilities. A C1-S1 View presents a simple mapping of services to capabilities, showing which services contribute to which capability.

Usage

• Service Specification & Planning.
• Governance.

Representation

• Tabular.
• UML.

Detailed View Description

A C1-S1 can be presented as a diagram showing tracing relationships from capabilities to services.

Figure 3-15

A C1-S1 can also be presented as a matrix with capabilities on one axis and services on the other.

The relationship between capability and service is many-to-many. A given service may provide one or more capabilities, or a given capability may be provided by more than one service. Note that if a combination of services are required to deliver a certain capability, this should be modelled using a combination of L2, Logical Scenario, (to map the capability to a node) and L4, Logical Activities, (to orchestrate the services against activities performed by the node).
